Low-pressure water purifying pipeline as well as water purifying device thereof and water purifying method

Abstract

The invention discloses a low-pressure water purifying pipeline as well as a water purifying device thereof and a water purifying method. The pipeline comprises a water faucet, and a water inlet end of the water faucet is connected to to-be-purified water, wherein a low-pressure switch, a primary filter element, a water pump, a secondary filter element, and a wastewater switch connected to a wastewater outlet of the secondary filter element, are sequentially connected with a water path of a water outlet end of the water faucet; when the water faucet is opened, the low-pressure switch is triggered to open, so that water sequentially passes through the primary filter element, the water pump and the secondary filter element; and purified water flows out from a purified water outlet of the water faucet, and wastewater is discharged from the wastewater outlet of the secondary filter element. Compared with the prior art, according to the low-pressure water purifying pipeline as well as the water purifying device thereof and the water purifying method disclosed by the invention, the low-pressure switch is used for control, so that cost of a high-pressure switch is saved; a control water path of a total water source and a purified water source inside the water purifying device is opened by the water faucet; the total water source is opened; the purified water source is opened; and thelow-pressure switch of a machine starts, so that the machine starts to work.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a low-pressure water purification pipeline, a water purifier and a water purification method thereof. Background technique [0002] At present, households often use more than 400G reverse osmosis pure water machines. During water production, the high-pressure switch controls the opening and closing of the machine, and the high pressure is stored inside the machine. However, conventional large-flow water purifiers are prone to repeated machine startup and water leakage after the water production is completed. The main reason is that there is a certain amount of water pressure inside the machine, which can easily cause water leakage from the water pipe joint and the sealing ring of the filter bottle. When the high-pressure switch of the machine stops working, if the pressure is unstable, it is easy to cause the machine to start repeatedly. Contents of the invention [00...
